基于單片機(jī)stc89c51制作的電子萬(wàn)年歷 畢業(yè)論文

1、I電子萬(wàn)年歷的設(shè)計(jì)與制作電子萬(wàn)年歷的設(shè)計(jì)與制作摘要本設(shè)計(jì)是電子萬(wàn)年歷。具備三個(gè)功能：能顯示：年、月、日、時(shí)、分、秒及星期信息，并具有可調(diào)整日期和時(shí)間功能。本論文選用的是單片機(jī)STC89C51來(lái)實(shí)現(xiàn)電子萬(wàn)年歷的功能。該電子萬(wàn)年歷使用12MHZ晶振與單片機(jī)STC89C51相連接通過(guò)軟件編程的方法實(shí)現(xiàn)了以24小時(shí)為一個(gè)周期，同時(shí)顯示小時(shí)、分鐘和秒的要求。利用單片機(jī)定時(shí)器及計(jì)數(shù)器產(chǎn)生定時(shí)效果通過(guò)編程形成數(shù)字鐘效果，再利用數(shù)碼管動(dòng)態(tài)掃描顯示單片機(jī)

2、內(nèi)部處理的數(shù)據(jù)。同時(shí)通過(guò)端口讀入當(dāng)前外部控制狀態(tài)來(lái)改變程序的不同狀態(tài)，實(shí)現(xiàn)不同功能。電子萬(wàn)年歷設(shè)計(jì)與制作可采用數(shù)字電路實(shí)現(xiàn)也可以采用單片機(jī)來(lái)完成。若用數(shù)字電路完成所設(shè)計(jì)的電路相當(dāng)復(fù)雜大概需要十幾片數(shù)字集成塊其功能也主要依賴于數(shù)字電路的各功能模塊的組合來(lái)實(shí)現(xiàn)焊接的過(guò)程比較復(fù)雜成本也非常高。若用單片機(jī)來(lái)設(shè)計(jì)制作完成由于其功能的實(shí)現(xiàn)主要通過(guò)軟件編程來(lái)完成這樣一來(lái)就降低了硬件電路的復(fù)雜性從而使得其成本降低更適合自主研發(fā)。該電子萬(wàn)年歷以單片機(jī)ST
